ipv4: Avoid use of signed integers in fib_trie code.
GCC emits all kinds of crazy zero extensions when we go from signed
int, to unsigned short, etc. etc.
This transformation has to be legal because:
1) In tkey_extract_bits() in mask_pfx(), the values are used to
perform shifts, on which negative values are undefined by C.
2) In fib_table_lookup() we perform comparisons with unsigned
values, constants, and additions. None of which should
encounter negative values.
